Format Tab (Custom OFDM)
The Format tab of the Custom OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. Demodulation Properties dialog box lets you configure the demodulator for Custom OFDM signals. These are the parameters necessary for the VSA to lock on to and demodulate the test signal.
The Format tab dialog box enables you configure these buttons and parameters:
- Preset to Standard
- Load Pilot IQ Values...
- Load Preamble IQ Values...
- Load Resource Map...
- Load Resource Modulation...
